Most Helpful Guy
For regular jobs, I don't necessarily think people get hired BECAUSE they are good looking. I think they get hired because of what their good looks can bring. E.g. if you're a waitress or barmaid or something along those lines then I think you're more easily able to attract customers because you're attractive. When you can bring in more customers you're gaining more business in such a situation.
I think for a regular job there is some sort of balance between experience/qualifications and looks. E.g. going back to the waitress/barmaid position. Let's say you have 2 girls who are applying for that job. The first girl has 55% of the relevant experience but is an average looking girl. The second girl has 45% of the relevant experience but is attractive. The second girl is more likely to be hired because she has the looks to bring in the business and her experience level is not that much lower than the first girl.
On the other hand, if the first girl had 90% of the relevant experience she would be hired over the first girl because her experience is significantly better than the second girl. Now, that doesn't mean she would definitely get the job. Some managers (especially if men) are suckers for beautiful women. So it all depends on who's hiring too. It's also about who you know as well. I find these days it's easier to get a job if you have the right connections rather than applying for a job where you don't know anybody.
